IMPROVEMENT IN MOLE-PLOWS.

Specification forming part of Letters Patent N0. 25,988, dated November 1, 1859.

To all whom it may concern:

Be it known that I, GEORGE WHI'rcoMB, of Springtiehbin the countyoi'Olarke and State ofOhio, have invented a ncwand useful Improvement in Mole-Flows, of which the following is full and exact description, reference being had to the accompanying' drawings, and to the letters marked thereon.

Figure l is a perspective view showing-the mold complete, and Fig. 2 a section showing the mold cut longitudinally through the center and exhibiting the construction and arrangement of the same.

A is a draft-beam which holds the cutter B, to which the front ofthe mold C is attached.

D,E, F, G, H, and I are concave rings strung 'upon the chain J and held by the nut Il', having bearings R R RR R It R. Therings D, E, F, G, H, and I fit into each other in such a manner as to resemble the body of a serpent. When the mold is bent the rings or sections pass over each other, similar to the rings or scales upon the serpent. Theadvantage thus to be derived is obvious fromthe fact that the mode of its construction gives it a free elastic serpentine movement in every way, giving it the capability of going around stumps, stones, hillocks, or any other obstruction Without injuring the face of' the ditch, the cavity being left perfectly smooth, for by the exibility gained by this improvement in mole-plows a perfect ditch can be made circuitously in the diameter of eight feet.

What I claim, and desire to secure by Letters Patent, is t The construction of a flexible mold by the combination ot'sections which are not attached to cach other, but by being held in place by the chain J or its equivalent, as set forth.
